Lua standalone is my favourite interactive language, so I like modules
that print
something informative when you require them. I like them callable too: function,
callable table or userdata, it does not matter.

E.g.

> mymod = require "mymod" -- prints a welcome message

If for non-interactive use you want to suppress the message, that
can be done by providing an option, e.g.

> mymod = require "mymod" "silently"
